Description
Summary:A newly developed moving-particle method is extended to solve the incompressible axisymmetric. Besides the particle moving strategy to deal with the flow convection term, a complementary Eulerian mesh is inserted into the particle cloud to realize the pressure-related operators. Therefore, the computational particles can be treated merely as observation points rather than material ones in terms of enforcement of the mass conservation constraint. Extension to solve axisymmetric problems becomes straightforward as long as the flow diffusion operator and symmetric boundary condition are appropriately resolved. To validate the formulation, computations are carried out by solving some benchmark problems. Numerical results are scrutinized by comparison with available analytical, numerical, or experimental data. It is shown that the proposed moving-particle method (MPPM) can furnish reasonable simulations for incompressible axisymmetric flows.
